One of the bigger decisions we had to make when coming to the Galapagos Islands was which one of the three available anchorages we wanted to stop at. As expected, the islands are highly regulated and traffic closely monitored. Private vessels may land at either Puerto Baquierizo Mareno on Isla San Cristobal or Puerto Ayora on Isla Santa Cruz and request to stay for up to 20 days, limited to the port of entry only. To stay longer (up to six weeks) and visit other ports, including Puerto Villamil on Isla Islabella a special permit called an Autografo is required. We did not have the time nor wanted to subject Jessie to a prolonged stay confined aboard so knew that we would only be able to go to one port.
But which one? Which has the provisions necessary for the next leg of our trip? Which offered worthwhile shore side excursions? Which port was the safest and most comfortable? After consulting our rather extensive ships' library we chose to go Isla San Cristobal in order to see the Galapagos tortoises, swim with the Galapagos sharks, hopefully see some of the various finches that Darwin documented as well as the Galapagos mockingbird, various booby colonies and some interesting geological formations.
After landing and clearing in we found out that we were restricted to only two different tours - the tortoise breeding station and diving with the sharks. Other tours offered by local operators to the more remote sites had recently been cancelled by the National Park. The only way to see these locations was with one of the large cruise ships travelling through the area. How it was determined that disgorging 300 people at a site is more ecologically friendly than showing eight people around is hard to figure out, until you factor in the access fees the larger tour operators pay. The Galapagos Islands are not free of political and bureaucratic persuasion.
We got together with the crews from three other boats in the bay and organized our own trip to the tortoise breeding station on the other side of the island, 30 kilometres away. We arrived at the morning feeding time and were lucky to see several mature and very large tortoises in their natural enviornment. The breeding station has been in operation for several years now with a very good success ratio. The goal is to bring the Galapagos tortoise clear of the endangered species and become self sustaining after nearly being decimated over the past five centuries. At the station, the park rangers collect the fresh eggs to protect them from predators such as feral cats and rats and place them in incubators until ready to hatch. The eggs are then returned to the nest in the same orientation as when originally laid and eventually the young tortoise breaks through the shell and has a look around.
The hatched tortoises are confined to pens until they are 8 to sometime 15 years old. They don't grow much over that first decade, possibly reaching 12 to 15 centimetres in width. As they mature, the tortoise are eventually released into the nearby native brush where they forage around themselves supplemented with the food provided by the park rangers every few days. The mature, 25 to 40 year old tortoises that we saw were up to one metre across their shell and weighed 40 to 60 kilograms. The whole breeding facility was very well run and has so far been successful in helping to stabilize the tortoise population.
